Project 2 Thermal modeling of battery pack

The below modell has been generated to study the characteristics of Battery models connected in series.

The Input parameters are given as shown below:

The Simulation results are observed as follows:

It is to be noticed, that the temperature of the cells remains constant, although the heat generated varies depending on the assembly topology

Worst case scenario:

Now one of the cell parameters will be varied, assuming that the Cell is worn out or defective.

Hence the Internal resistance offered by the cell increases and the capacity of the cell reduces.

It is observed from the results that temperature of the defective cell increases and not in pace with the other cells.

The Capacity and hence the Heat produced from the cell deviates from the normal Modell shown above.

It is evident that the Modell is sensitive to changes in characteristics of the Individual cells.
